Item details:

Description:
Upgrade your AEG's fps to 380 to 410fps. It is highly recommended to upgrade plastic bushings and spring guide to metal bushings and spring guide with this product. Also, it would be wise to upgrade plastic pistons to polycarbonate piston; plastic piston heads to duracon piston heads; and standard gears to reinforced steel gears. Finally for best results a battery upgrade is also recommended.
